Nothing can take away joy from the man who has right understanding.

Joy and sorrow are each part of the other.

Joy is not something brought from outside. It belongs to us, but it manifests to us as the result of certain actions.

He who can quicken the feeling of another to joy or to gratitude, by that much he adds to his own life.

Joy and sorrow both are for each other. If it were not for joy, sorrow could not be; and if it were not for sorrow, joy could not be experienced.
